5G is the 5th generation wireless technology that provides radically faster wireless internet speeds along with ultra-reliable low latency connectivity. It comes in three types - low-band, mid-band, and high-band. 5G offers higher speeds, greater capacity, and lower latency than 4G. Key uses and applications of 5G include entertainment and multimedia streaming, supporting the Internet of Things, and enabling remote access and control of machines. While 5G networks have launched in some countries since 2019, concerns remain about the potential health effects of the higher microwave frequencies used by 5G.

7. AVAILABILITY OF 5G
 5G network was launched in parts of the world since 2019
 Authorities are the availing the 5G spectrum to industry players
 A number of countries have rolled out 5G including 11 African countries
 More and more 5G compliant devices are been manufactured
 It is estimated that 5G networks will cover one-third of the world’s population
by 2025

9. 5G DATA SECURITY
• More flexible framework
1. Unified
authentication of
devices.
2. Network slicing
• Tighter security
1. User plane integrity
protection.
2. Subscription
credentials in secure
hardware elements
• Enhanced privacy
1. Ciphered user,
devices and data.
• Data ownership
1. Link device owner to
data produces.
2. Local/remote device
management
• Data provenance
1. Establish a single
version of facts
• Data governance
1. Policy control and
enforcement
2. Audit trail of
transactions on data

10. COMMENT ON GLOBAL HEALTH CONCERNS
 High performance 5G is proposed to operate on a high microwave
frequency of 30GHz – 300GHz
 Acceptable RF exposure for the human body is 30MHz – 300MHz
 Previous generations of wireless networks were proven to be
associated with a number of health conditions
 It is conclusive that 5G which is said to operate on a higher
frequency will certainly cause some health complications ranging
from mild discomfort to life threatening conditions (Ronald et al.,
2020).

11. SOME KEY WORDS
 IoT – Internet of Things
 Autonomous Cars – Cars that do not need a driver to drive it
 Smart City –
 Network slicing -

12. CONCLUSION
I think 5G will be an awesome network.
However, researchers must be interested in
network technologies that are as cool as 5G but
with minimum ERF effects.
